Conveyer belt



Patented July 28, 1931 JOHN C. ANDERSON, F KEYPORT, NEW JERSEY CONVEYER BELT Application led January 2, 1929. Serial No. 329,022.

My invention relates to conveyers and more particularly to those of the woven wire type, such as are formed by helically interlaced strands of wire that are disposed '5j transversely of the longitudinal axis of the belt and such as are of the general character shown, for example, in Patent No. 1,583,046, issued to Henry W. Ingle on May 4, 1926 and in my prior application, Serial No.

207 ,844, filed July 23, 1927.

In my said copending application, I have set forth some of the advantages of a con-l veyer belt formed of helical strands of wire having belt sections divided on a line ex- \l5 tending centrally and longitudinally of the said belt, the sections on alternate sides being formed with right and left hand helixes, respectively. This invention is an improvement on the device of my said co- 2D pending application.

One object of this invention is the provision of a conveyer belt having the manifold advantages of the conveyer belts described in my copending application and being so constructed that there is no tendency for the belt to lift or bend at the center, or to have the center thereof raised above the sides of the belt. A further object is to provide a longitudinally divided $0 woven wire conveyer, having a right-hand weave on one side and a left-hand weave on the other, which will be of substantially the same character, strength and rigidity at the juncture between the two weaves as throughout each weave.

Further objects will be apparent from the following specification and claims.

In order to more clearly explain the invention, one embodiment thereof is shown in the accompanying drawings in which:

Fig. 1 is a plan view of a portion of a conveyer belt formed according to my invention; and

Fig. 2 is a view in elevation of the belt shown in Fig. 1. w

In the embodiment shown every alterlnate wire extends the full width of the conveyer and on one side of its center is formed of helixes having a right-hand twist,

and on the other side of similar helixes having a left-hand twist. 'Ihe intervening wires extend only to the center v'of the conveyer and' the inner ends thereof are there secured to one of the first-named wires at the point at which the right-hand twist is changed to a left-hand twist.

Referring particularly to the drawings, strands of helically wound wire 11 extend laterally all the way across the conveyer belt', having portions 12 extending from the right-'hand edge of-the belt to the center thereof and portions 13 extending from the center to the left-hand edge of the belt. The portions 12 are formed with aright-'hand twist while the portions 13 are formed with a left-hand twist. Each of the wires 11v` is one continuous strand Vand is formed with a loop 14,. joining the two sections 12 and 13. Wires 15 are connected to the righthand sections 12 by being threaded thereinto and these wires like the sections 12, are formed with helixes having a right-hand twist. They are connected to the outside end of the wires 11 by loops 16, andto the loops y14: by loops 17. Wires 18 having helixes of left-hand twist, but otherwise similar to the wires 15, are connected to the portions 13 by being interwoven therewith, and by loops 19 connected to the outer end of the portions 13 of the wires 11 and loops 20 connected to the loops 14.

It is to be'understood that the above vdescribed embodiment of the invention is for the purpose of illustration only and various changes may be made therein without departing from the spirit and scope of the invention.

I claim as my invention: 1. Conveyer belt structure comprising helically woven wires, extending transversely of the belt and each of said wires having one portion thereof formed with left-hand helixes and another portion formed with right-hand helixes, and other wires joined to the first-named wires.

2. In conveyer vbelt structure, wires extending transversely of av conveyer, 'said wires being formed of spirals, and each having one portion thereof with a spiral 'reversed as to another portion, and additional Wires connected to the first-named Wires.

3. A helically woven wire structure having alternate wires extending transversely all of the way across the structure, and having intervening wires extending only to the longitudinal median line of the said structure.

4. A conveyer belt formed of woven Wirefabric, this fabric com rising a plurality of alternate Wires exten ing all of the Way laterally of the said structure, each having onehalf thereof formed with left-hand heliXes, and the other half formed with right,- hand helixes, and a plurality of intervening Wires of right-hand helixes joining and connecting the right-hand helixes of the iirst-named Wires, and a plurality of intervening Wires of left-hand helixes joinin and connecting the left-hand helixes of the said first-named wires, the total length of two intervening Wiresbeing substantially equal to the length of the said first-named wlres.

Signed at Keyport, N. J., this 29th day of December, 1928.
